Abstract
The utility model particularly provides an automatic control anti-freezing power transmission line, and solves problems that an existing power transmission line is time-consuming and labor-consuming in maintenance in rainy and snowy weather, a maintenance device is liable to be damaged and the power transmission line is liable to be damaged by pressure. A power transmission line body comprises a cable core. The external side of the cable core is wrapped with an insulating layer. The external side of the insulating layer is wound by a high-impedance conductive wire layer. The external side of the conductive wire layer is wrapped with a heat-conducting plastic layer. A control system comprises a temperature sensor, a relay and an STC89C52 single-chip microcomputer. The cable core is connected in parallel with a series connection branch which is connected in series with the relay and the conductive wire layer. The input end of the relay is connected with the output end of the STC89C52 single-chip microcomputer. The input end of the STC89C52 single-chip microcomputer is connected with the output end of the temperature sensor. The automatic control anti-freezing power transmission line is reasonable and reliable in structural design so that phenomena that an external deicing device is liable to be damaged and safety is influenced are eliminated without artificial maintenance in deicing, labor intensity is mitigated, normal use of the cable is guaranteed, and thus the automatic control anti-freezing power transmission line has advantages of being simple in structure, convenient to process and low in cost.
Description
Technical field
The utility model relates to ultra-high-tension power transmission line, is specially a kind of automatic control antifreeze power transmission line road.
Background technology
Current high-tension line deicing device for melting snow is all external, and external device is subject to external influence very large, holds very much device is damaged, and affects safety.
Especially change extreme in the situation that at current weather, sleet, snow etc. occur more, cause great impact to electric power transfer, in prior art cable cannot the anti-sleet of automatic control, snow, in the situation that there is sleet snow, safeguard not in time, tend to damage by pressure the equipment such as cable.
Summary of the invention
The utility model exists when meeting sleety weather on the way and safeguard in order solving existing power transmission line wastes time and energy, fragile attending device and the problem of easily damaging transmission line by pressure, and a kind of automatic control antifreeze power transmission line road is provided.
The utility model is to adopt following technical scheme to realize: automatic control antifreeze power transmission line road, comprise transmission line body and control system: transmission line body comprises cable core, cable core outside is enclosed with insulating barrier, insulating barrier outer felt is wound with the conductor layer of high impedance, and conductor layer outside is enclosed with heat-conducting plastic layer; Control system comprises temperature sensor, relay and STC89C52 single-chip microcomputer, on cable core, be parallel with the series arm that is serially connected with relay and conductor layer, the input of relay is connected with the output of STC89C52 single-chip microcomputer, and the input of STC89C52 single-chip microcomputer is connected with the output of temperature sensor.
In ambient temperature too low or meet wind and snow weather in, temperature signal is transferred to STC89C52 single-chip microcomputer by transducer, after STC89C52 single-chip microcomputer is processed by temperature comparison program (conventional design that temperature comparison degree is those skilled in the art), the connection of control relay, now the conductor layer of high impedance can produce a large amount of heat, and the heat of generation is conducted heat and melted the icing on cable by heat-conducting plastic layer; After temperature reaches more than fusing point, temperature signal is transferred to STC89C52 single-chip microcomputer by transducer, after STC89C52 single-chip microcomputer is processed by temperature comparison program (conventional design that temperature comparison degree is those skilled in the art), the disconnection of control relay, so not only do not affect the transmission quality of cable, and can effectively remove the icing of cable, when having overcome existing power transmission line and meeting sleety weather on the way and safeguard, exist waste time and energy, fragile attending device and the problem of easily damaging transmission line by pressure.
The utility model reasonable in design is reliable, stopped external deicer fragile, affect safe phenomenon, and do not need manually to go to safeguard deicing, when reducing labor intensity, ensure the normal use of cable, had advantages of simple in structure, easy to process and cost is low.
